Characteristics-
PSA:
75.76000
XLogP3:-0.03
Appearance:N-nitroso-n-methylurea appears as pale yellow crystals or light yellow moist powder. (NTP, 1992)
Density:1.5±0.1 g/cm3
Melting Point:124 °C (decomp)
Boiling Point:164.3±23.0 °C at 760 mmHg
Flash Point:53.1±22.6 °C
Refractive Index:1.545
Water Solubility:14.56g/L(temperature not stated)
Storage Conditions:2-8°C
Vapor Pressure:Non-volatile (NTP, 1992)
Toxicity:LD50 oral in rat: 110mg/kg
Explosive limit:Material stored at 20 deg C exploded after 6 months. Explosive decomposition and ignition of solvent ether occured when 50 g of the compound in a nickel spoon was being added to 40% potassium hydroxide solution to generate diazomethane.
Henrys Law Constant:Henry's Law constant = 9.9X10-11 atm-cu m/mol at 25 °C (est)
Experimental Properties:Decomposes to diazomethane in alkaline solutions; stability in aqueous solutions is pH dependent: pH 4.0, half-life 125 hours; pH 6.0, half-life 24 hours; pH 7.0, half-life 1.2 hours; pH 8.0, half-life 0.1 hours; and pH 9, half-life 0.03 hours (at 20 °C).|Hydroxyl radical reaction rate constant = 1.6X10-12 cu cm/mole-sec at 25 °C (est)
Air and Water Reactions:Sensitive to humidity and light when pure. Insoluble in water. Slowly decomposes in water. Alkaline hydrolysis produces a highly toxic, irritating and explosive gas.
Reactive Group:Amides and Imides
Reactivity Alerts:Water-Reactive
Reactivity Profile:N-NITROSO-N-METHYLUREA is incompatible with strong acids and bases. Also incompatible with water and nucleophilic reagents. Alkaline hydrolysis produces a highly toxic, irritating and explosive gas. Can detonate with (potassium hydroxide + methylene chloride) (NTP, 1992).
